Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-9, A waterproof socket, including a socket body 1, the socket body 1 includes a shielding shell 11, an inner shell 12, a fixing seat 13, an insulating substrate 15, a card seat 16 and a stabilizing seat 18. A plurality of terminals 17 are arranged on both the top and bottom of the insulating substrate 15. One end of the insulating substrate 15 is provided with a connecting seat 151, and a ring groove 152 is arranged on the connecting seat 151. The fixing seat 13 is located on one side of the insulating substrate 15. The outside of the connecting seat 151 is sleeved with a card seat 16. One side of the fixing seat 13 is provided with an inner shell 12 sleeved on the outside of the card seat 16. The outside of the inner shell 12 and the fixing seat 13 is jointly sleeved with a shielding shell 11. The top of the fixing seat 13 is provided with an injection hole 132, and an annular dispensing groove 2 is arranged between the fixing seat 13 and the insulating substrate 15.

[0028] As a specific technical solution of this embodiment, on one side of the top of the inner wall of the ring groove 152, there is an injection groove 153 opposite to the injection hole 132. The stabilizing seat 18 is embedded at the bottom of the fixing seat 13. One side of the stabilizing seat 18 is provided with an overflow port 181 whose bottom end extends to the bottom of the inner shell 12. The setting of the annular dispensing groove 2 is used for injecting glue for sealing. At the same time, the glue can enter the inside of the ring groove 152 through the injection groove 153 to seal between the card seat 16 and the connecting seat 151. The glue can also enter the gap between the fixing seat 13 and the stabilizing seat 18, ensuring the relative stability between the fixing seat 13 and the stabilizing seat 18, and further ensuring the sealing performance. The overflow port 181 is provided. When there is air residue in the annular dispensing groove 2, air holes are likely to be generated during dispensing, and holes are generated inside the glue after curing, affecting the sealing effect of the product. By setting the overflow port 181, the air in the dispensing groove can be discharged during dispensing, which is beneficial to the filling of the glue, making the glue filling more full, improving the product quality, and at the same time, the yield of the product is also improved. Refer to Figure 9 , Figure 9 It is a schematic cross-sectional view after injecting glue into the annular dispensing groove 2.

[0029] As a specific technical solution of this embodiment, one end of the terminal 17 on the top of the insulating substrate 15 penetrates through the inside of the annular dispensing groove 2 and the fixing seat 13 and extends to the bottom of one side of the fixing seat 13. One end of the terminal 17 on the bottom of the insulating substrate 15 penetrates through the inside of the annular dispensing groove 2 and the stabilizing seat 18 and extends to the bottom of the stabilizing seat 18. The ends of the terminals 17 on the top and bottom of the insulating substrate 15 away from the insulating substrate 15 are welded to the circuit board. One end of the terminal 17 located on the top and bottom of the insulating substrate 15 is arc-shaped, which can reduce the jamming during plugging and unplugging. At the same time, it avoids the warping of the end of the terminal 17, increasing the service life.

[0030] As a specific technical solution of this embodiment, a convex ring 134 is provided on one side of the fixed seat 13. One end of the inner shell 12 is clamped with the convex ring 134, and the other end extends to the outside of the shielding outer shell 11 and is provided with a sealing ring 121. The number of the sealing rings 121 is not less than one. After the initial clamping of the convex ring 134 and the inner shell 12, the stability of the inner shell 12 is ensured, and at the same time, it is convenient for the subsequent glue injection operation. Subsequently, fixing is carried out by injecting glue, which further ensures the connection stability between the inner shell 12 and the fixed seat 13.

[0031] As a specific technical solution of this embodiment, a connecting plate 19 located between the top terminal 17 and the bottom terminal 17 is further provided inside the insulating substrate 15. At both ends of one side of the connecting plate 19, clamping protrusions 191 protruding to both ends of the insulating substrate 15 are respectively provided. The other side of the insulating substrate 15 penetrates through the annular dispensing groove 2 and winds from the top of the stable seat 18 to one side of the stable seat 18. The setting of the clamping protrusions 191 can be clamped with the clamping groove 131 inside the Typec plug when mating with the Typec plug, ensuring the insertion stability between the Typec plug and the inner shell 12. And after the Typec plug is inserted into the inner shell 12, it abuts against the sealing ring 121, ensuring the sealing performance at the connection between the Typec plug and the inner shell 12. Refer to Figure 7 , the connecting plate 19 also passes through the annular dispensing groove 2 and a number of irregular holes are provided on the connecting plate 19. When the annular dispensing groove 2 is injected with glue, the glue fills the holes, further ensuring the stability of the connecting plate 19.

[0032] As a specific technical solution of this embodiment, a fixed enclosure 161 sleeved outside the insulating substrate 15 is provided on one side of the card seat 16. A number of injection grooves two 154 opposite to the annular dispensing groove 2 are provided at the bottom of one side of the annular groove 152. The setting of the injection grooves two 154 enables the glue to quickly fill the inside of the annular groove 152. During processing, sealing glue is injected through the injection hole 132. The glue enters the annular dispensing groove 2 through the injection hole 132. The glue inside the annular dispensing groove 2 enters the inside of the annular groove 152 through the injection groove one 153 and the injection grooves two 154. The product adopts an annular conduction process to ensure full injection of the glue. After the glue is cured, the stability of the shielding outer shell 11, the inner shell 12, the fixed seat 13, the insulating substrate 15, the card seat 16, the stable seat 18 and the connecting plate 19 can be realized.

[0033] As a specific technical solution of this embodiment, two card slots 131 are provided on the top of the fixed seat 13, which are respectively located on both sides of the injection hole 132. Two first buckles 111 are provided on the top of the shielding housing 11, which are respectively clamped inside the two card slots 131. One end of the shielding housing 11 is provided with a rear baffle 112 located on one side of the fixed seat 13. An avoidance hole 115 opposite to the injection hole 132 is provided between the rear baffle 112 and the shielding housing 11. The avoidance hole 115 is used to avoid the injection hole 132, facilitating the staff to inject glue through the injection hole 132. Two first clamping plates 113 are provided at both ends of the rear baffle 112, which are respectively attached to both sides of the shielding housing 11. Two second buckles 114 are provided on both sides of the shielding housing 11, which are respectively clamped inside the two first clamping plates 113. The cooperation between the card slot 131 and the first buckle 111, the cooperation between the second buckle 114 and the first clamping plate 113, and the cooperation between the second clamping plate 116 and the fixed seat 13 ensure the connection stability between the shielding housing 11 and the fixed seat 13, making the shielding performance of the shielding housing 11 more stable. Combined with the cured glue, the overall stability of the product is further ensured.

[0034] As a specific technical solution of this embodiment, second clamping plates 116 with one end extending to the bottom of the fixed seat 13 are provided at the bottom of the shielding housing 11 below the two second buckles 114. The bottom of the fixed seat 13 is provided with at least one positioning post 133. The bottom of the shielding housing 11 and the rear baffle 112 are both provided with at least one pin 14, and can be installed on the circuit board through the positioning post 133 and the pin 14.

[0035] In summary, for this waterproof socket, sealant glue is injected through the injection hole 132. The glue enters the annular dispensing groove 2 through the injection hole 132. The glue inside the annular dispensing groove 2 enters the inside of the annular groove 152 through the first injection groove 153 and the second injection groove 154. The product adopts an annular conduction process to ensure that the glue injection is full. After the glue is cured, the connection sealing performance of the shielding housing 11, the inner housing 12, the fixed seat 13, the insulating substrate 15, the card seat 16, the stable seat 18, and the connecting plate 19 can be realized. At the same time, the overall structural strength of the product is greatly improved.
